Abstract

Plasma Extraction Transit Time (PETT) oscillation exists in the tail phase during the turn-off process of paralleled IGBT chips. The small signal behaviors of space charge region caused by injection of carriers is analyzed in this paper. Then, the relationship between package parasitic inductance and oscillating voltage range is investigated. The experimental results are in agreement with the calculated results for oscillation voltage range.
